Tri-Wing anti tamper bolt

Ran across some of these in a recent dig through the garage.
Tri-Wing anti tamper bolt.


Does DMS have screwdrivers for this?
If not, does anybody have drivers for this?

I may have that “never used bit” for that - I will looks through my various cabinets at home tonight and if not in the ‘mystery assortment’ at work tomorrow. It should be next to the the “clutch bit” that also was never used - similar to the tool for r & r of original rear fender fasteners on older GM Pickups circa 1950 ish.

A bit with that profile (but maybe not size) is in the bit sets commonly available at Harbor Freight.

It’s the bottom middle row of this picture from Amazon. This set is available at HF, as is a smaller set in a rubber block that has the same tri-wing bits.
